Which Husqvarna IPL or Manual Do I Use? 281 Brake Band

[dsell]

9220256 serial, so which IPL do I use to pick the proper brake band for the clutch cover? How do you know which one to get for 2000 since two variations exist but the ipl doesn't show the serial range? My guess would be, 1999 saw, use 1997-12 ipl, so 503704001 should be the correct band.
